Optimal Cropping

To improve farm incomes in developing countries, the foremost question that the farmer must address himself to is: what cropping pattern best uses the fixed resources in order to get the highest returns? During the last decade, the agricultural economists have shown great interest in applying the tools of linear programming to individual farms. Most of the studies conducted elsewhere have shown that, under existing cropping pattern, farm resources were not being utilized optimally on the small farms.[l, 4]. We conducted a survey in the canal-irrigated areas of the Punjab province of Pakistan1 to investigate into the same problem. This short note aims at identifying the opti¬mal cropping pattern and to estimate the increase in farm incomes as a result of a switch towards it on the sampled farms.

Krueng Jreue irrigation area is one of the oldest irrigation in Aceh Besar district, located in the District of Indrapuri, was inaugurated in 1972 by President Soeharto. Rice area irrigated by this irrigation is 4277.6 ha. Jreue Krueng irrigated areas have rice-rice cropping intensity of plants ranging from 158% to 156%. The intensity of these plants are still below the expected crop intensity, is equal to 200%. To increase the intensity of these plants, it is necessary to study the increased intensity of Krueng Jreue tanamana irrigation area by selecting the appropriate alternative cropping patterns according to the water balance. This study aims to determine the amount of discharge mainstay available on the weir, know the size of the crop water requirement for each alternative, determine optimal crop area that can be irrigated by water that is available, and conduct studies on water balance based cropping planned. Expected to describe the water balance of alternative cropping patterns were obtained. The method used in this research including data collection and data analysis to determine the mainstay discharge, water irrigation, cropping pattern and cropping intensity. The study results obtained by the intensity of the plants can reach 200% by the water supply system using the technical rotation irrigation area is divided into two groups. The first type, cropping season from October period to 2. The second class of the cropping season from November to 2.

An experiment was conducted at Bangladesh Rice Research Institute (BRRI) Farm at Rangpur during July 2014 - June 2016 to introduce a 4-crops pattern with the aim of increasing cropping intensity, productivity, income and soil fertility. The experimental design was RCB with 3 replications. Four cropping patterns were tested which were: CP1 = T. Aman (BRRI dhan62)-Potato (Cardinal)-Mungbean (BARI Mung-6)-T. Aus (BRRI dhan48), CP2 = T. Aman (BRRI dhan62)-Mustard (BARI Sorisha-14)-Mungbean (BARI Mung-6)-T. Aus (BRRI dhan48), Farmers’ improved practice (FIP) = T. Aman (BR11)-Potato (Cardinal)-Maize (NK 40) and Farmers’ general practice (FP) = T. Aman (BR11)-Boro (BRRI dhan28)- Fallow.  In T. Aman 2014, BRRI dhan62 produced  3.87 and 3.85 t ha-1 grain yields under CP1 & CP2 (4 crops systems), respectively; BR11 gave grain yield of 4.62 and 4.36 t ha-1 in FIP and FP (3 and 2 crop system), respectively. In T. Aman 2015, BRRI dhan62 produced grain yield of 4.23 and 4.19 t ha-1 in CP1 and CP2, and BR11 gave grain yield of 5.95 and 5.92 t ha-1 in FIP and FP, respectively. After T. Aman, potato yield was 24.66 t ha-1 in CP1 and 24.17 t ha-1 in FIP during 2014-15. In CP2, 2nd crop mustard yield was 1.16 t ha-1 and3rd crop mungbean yield was only 0.98 t ha-1.In CP1, 3rd crop mungbean yield was only 0.83 t ha-1. After potato in FIP, maize yield was 8.38 t ha-1. After T. Aman (BR11) in FP, grain yield of BRRI dhan28 was 5.42 t ha-1. The yield of BRRI dhan48 in CP1 and CP2 (as 4th crop) was 4.5 t ha-1. Similar results of different crops were obtained in 2015-16. The rice equivalent yield (REY) was found to be 30.05 & 35.95 t ha-1yr-1 in CP1 during 1st and 2nd yearfollowed by FIP (23.92 & 29.82 t ha-1yr-1, respectively). The REY was higher in 2nd year compared to 1st year. In 2014-15 the highest net return of Tk.2,42,560 ha-1 was observed in CP1 followed by FIP(Tk.1,58,380 ha-1); in 2015-16, the highest net return was in CP1 (Tk.2,16,960 ha-1) followed by FIP(Tk.1,24,620 ha-1). Potato based cropping pattern was thus, the most suitable and profitable pattern in this area. T. Aman (BRRI dhan62)-Potato (Cardinal)-Mungbean (BARI Mung-6)-T. Aus (BRRI dhan48) may, therefore, be the most suitable and profitable cropping pattern in medium high lands of Rangpur region. The Agriculturists 2017; 15(1) 116-126
